Scientists reveal mechanism that causes irritable bowel syndrome

Researchers have identified the biological mechanism that explains why some people experience abdominal pain when they eat certain foods. The finding paves the way for more efficient treatment of irritable bowel syndrome and other food intolerances. The study was carried out in mice and humans.

One small alcoholic drink a day is linked to an increased risk of atrial fibrillation

A study of nearly 108,000 people has found that people who regularly drink a modest amount of alcohol are at increased risk of atrial fibrillation, a condition where the heart beats in an abnormal rhythm. The study found that, compared to drinking no alcohol at all, just one alcoholic drink a day was linked to a 16% increased risk of atrial fibrillation over an average follow-up time of nearly 14 years.

The role of T cells in fighting cancer

Why do some hosts' immune systems reject tumors easily, while others have a harder time doing so? It depends on the types of the immune cells known as CD8 T cells and how a host's specific T cells match up with the neoantigens present in the tumor.

Research breaks new ground in understanding how a molecular motor generates force

A team of biophysicists set out to tackle the long-standing question about the nature of force generation by myosin, the molecular motor responsible for muscle contraction. The key question they addressed - one of the most controversial topics in the field - was: how does myosin convert chemical energy, in the form of ATP, into mechanical work? The answer revealed new details into how myosin, the engine of muscle and related motor proteins, transduces energy.

How plants produce defensive toxins without harming themselves

Scientists describe the biosynthesis and exact mode of action of diterpene glycosides in wild tobacco. These antiherbivory compounds attack the cell membrane. To protect themselves from their own toxins, tobacco plants store them in a non-toxic form. Autotoxicity and the protection against it seem to play a greater role in the evolution of plant defenses than previously thought.
